Self-cleaning anti-blocking magnetic gathering medium box, vertical ring high-intensity magnetic separator and self-cleaning method

The invention discloses a self-cleaning anti-blocking magnetism-gathering medium box, a vertical ring high-intensity magnetic separator and a self-cleaning method, the magnetism-gathering medium box of the high-intensity magnetic separator comprises two magnetism-gathering medium box bodies which are respectively a first sub-medium box and a second sub-medium box located on the inner side of the first sub-medium box; the end part of the magnetic medium A of the first sub-medium box movably penetrates through the non-magnetic side plate B of the second sub-medium box and then is connected with the non-magnetic side plate A; and one medium box body is provided with a bearing part used for bearing force applied by a power source, so that the two medium box bodies move relatively by applying force to the bearing part. By designing the magnetism gathering medium box, the magnetism gathering medium box can work under the action of a power source according to the structural characteristics of the magnetism gathering
